Risk analysis model for the ascent phase of scientific balloon operations
… People living in these areas are subject to risk from these operations. A model has been developed to predict the risk associated with the ascent phase of a balloon operation. This model includes all of the significant factors that affect ascent phase risk. The model is automated in a …

Quantitative Approach and Departure Risk Assessment for Unmanned Aerial Systems
… gives the user an accurate representation of the risk to 3rd parties on the ground associated with a given flight plan. The main area of focus was on large rotorcraft and fixed-wing aircraft that are used by the military and that have the potential to do large amounts of damage if a crash were to …

Model predictive control for ascent load management of a reusable launch vehicle
… balloon measurement procedures. Managing the mission risk caused by these uncertain wind measurements has always been important to control system designers. This thesis will describe a novel approach to managing structural loads through the combination of a Light Detection and Ranging (LIDAR) …

On-Orbit Pointing Risk Mitigation for the Agile MicroSat (AMS) CubeSat Laser Guidestar Payload
… optics (AO). During the science phase of the mission, it will establish a space-to-ground link with an AO-equipped ground station. Due to budget constraints and size, weight, and power (SWaP) limitations, the AMS Beacon was designed without gimbals or fast-steering mirrors, to utilize only …

Assessment of damage to thermal protection systems due to micrometeoroid and orbital debris impacts
… of this system, the number of impacts that cause mission failure due to micro-meteoroid and orbital debris damage is presented. This number differs based on the mission, so a methodology is presented to solve for this number. The methodology is comprised of two branches, the first branch solves …

An Approach to Fault Management Design for the Proposed Mars Sample Return EDL and Ascent Phase Architectures
… the spacecraft for different phases of the mission like Entry, Descent \& Landing (EDL) and MAV Launch given limited possible operator intervention. Fault protection (FP) encapsulates these autonomous system behaviors, which aim to protect the spacecraft by limiting or detecting and …

Enhancement of perception with the application of stochastic vestibular stimulation
… would improve crewmember safety and decrease mission risk. The goal of this research was to investigate the potential use of electrical stochastic vestibular stimulation (SVS) as a sensorimotor aid to lower vestibular thresholds and improve manual control. We hypothesized that low-level, …

Cyber-Physical-Social Systems for Autonomous Defense: Enabling Mission-Centric, Adaptive, and Anytime Intelligence
… Systems (CPSSs) are rapidly transforming mission-critical domains such as transportation, defense, emergency response, and smart infrastructure by enabling real-time sensing, decentralized control, and autonomous decision-making. Yet the increasing complexity, interconnectivity, and …
